material, to form a water tight connection between the To all whomit may concern:

'Be it known that I, REUBEN B. BENJAMIN, a citizen of thtiUnited States, residing at Chicago, in the county of ("ook and State'of lllinois, have invented new and useful linprovements in 'Electric Lamp Sockets, of which the following is a full, clear, concise, and exact description, refercncebeing had to the accompanying mounta large number of incandescent lamps upon a single supporting plate or base.

The other objects and novel features of my invention will more fully appear from the accompanying description and drawings in which like reference characters are used to indicate like parts in the several figures.

. Referring to the drawings, Figure 1 is a front or face view of one form of my improved socket; Fig. 2 is a secti'onal view on the line 2-2 of Fig. 1; Fig. 3 is a sectional view on the line 33 of Fig. l,' showing.the socket at clust er socket embodying my invention; Fig. 12 is aim proved socket; Fig. 5 is a detail -'yiew-of'the lamp receiving shell; 6 is a face view of another form of my invention; Fig. 7 is a sectional view on the line 77 of Fig. 6, showing the socket secured to a supporting plat c: Fig. 8 is a sectional view on the line 8 '8 of Fig. 6; Fig. 9 is a rear view of my invention; Fig. 10 is a side elevation thereof; 11 is a bottom plan view of a sect ional view on the line 12-12 of Fig. 11; Fig. 13 is a sectional view of another form of my invention adapted forusc as a ceiling cluster; and, Fig. 14- is a partial sectit mal view of another form of cluster embodying my invention.

Referring to Figs. 1 to 5, inclusive,'a base 1, made of porcelain or other suitable insulating material, is provided with a flange 2, having suitable openings 3, formed therein for securing the socket to a support 4,

screws 5 being preferably provided forthat,purposc.

The supporting ram is preferably formed of metal although anyother suitable material may be used. An annular projection (i may be l'ormed upon the flange 2 which projects slightly beyond the supporting plate 4,

and serves to insulate the lamp contacts from said sup.- porting plate. An annular recess 7 is preferablyprovidcd in the face of the flange 2, which is arranged to receive a gasket or washer of rubber or other suitable flange 2 and the supporting plate 4.

Formed in the face of the insulatin g bas l. is a ,lcccss I or receptacle 8, a screw threaded lamp receiving shell 9 being disposed in the bottom of said receptacle. and securedtherein in any suitable manner, as by the bolts 10, 10, extending through the base. These bolts also secure in position a contact plate 1.1 which extends through an aperture 12 formed in the side of the iustt lating base 1, and carries a binding screw 13 for securingthe feed wire thereto. An aperture 14 is formed in the opposite side of the basal, to accommodate the center lamp contact-plate 15,'which is held in position by the bolt 1o, andhas one end thereof preferably disposed upon aproje ction 17 carried by the base 1 whereby the center contact is insulatedfrom the lamp receiving shell'9' and thecontact plate 11. The contact plate l5 also carries'a suitable binding screw 18 forsecuring a feed wire thereto. 7

The lamp receiving shell9 has a cut out portion 19 formed in the bottom thereof to accommodate the contact platesll and. 15,. the boltslt), 10, entering said shell upon either side of said out out portion as shown in Fi .5.

, It will be understood that any desired number of the sockets above described maybe mounted upon a continuous supporting plate, and that said socket/s may be arranged in any desired manner thereon. The feed wires pass from one socket to another being connected to the binding screws carried by tliecontact plates 11 and 15.

Referring toFigs. 6 to 10, inclusive, the flange 2 carried by the insulating base 1. is elliptical in form to'permit the sockets to be mounted closely together upon a supporting plate 20. The face of the flange 2 is preferably beveled to conform to the concave supporting shell 20, although the socket may be adapted for nse -witl1 any desired form of support, and any suitable means of securing the sockets thereto may be adopted in lieu of the bolts 3, 3. The grooves or depressions 21,

- 21, are formed in the sides of tin base 1., to afford access to the binding screwsl3 and 1 and t permit the feed outer casing 22 is centrally suppm-tcd by a tripod 23, or

other suitable means, attachcdto a pipe or conduit 24. Formed about. the periphery of the casing 22 are a plurality-oi apertures or openings; opposite which the' inf sulating bases 1 are disposed, the receptacle 8, formed in said bases, being adapted to register with said apertures,v and the flanges 2 of said bases being secured to a single piece of metal and having a central openingior l thcconduit 24 is provided for the socket. Tholeading in wires for the socket are arranged to pass through (onduit 24 and are secured one to either side of the circuit,

' the ring and center contacts of the lamp having been;

. previously wired as shown in Fig. 12.

flange 23 formed integrally therewith, which is adapted to support the clustcr directly upon the ceiling or other v suitable support by means-of the screws 24, 24. A fiat disk 25 ofinsulating material having an opening 27 for the leading in wires is disposed between the ceiling or support 26, and the interior of the cluster. i

In Fig..14 I have illustrated my invention as adapted for use with another form of cluster, which isjshow'n as comprising a supporting plate 28, preferably stamped from a single sheet of metal and having suitably disposed annular faces 29 and 30, provided with apertures registering with the receptacles formed in the insulating bases I The supporting plate or casing '28 is prefrably supported in position by a ring 31 secured to-said plate by screws (not shown) or in any-suitable manner,

I and having radially converging arms 32 integrally connected thereto to which is connected a suitable pipe or support 33, which also constitutes a conduit for the v feed wires. A suitable casing or cover 34, preferably 35 formed from a single piece of metaland having a centrally disposed aperture formed therein for the conduit or support- 33, is provided for the casing or supporting plate 23. v

Whil I have illustrated my invention in connectid'n 40 with a substantially semi-spherical casing, itwill be understood that any desired form oi casing or support I may b used. and that my invention is applicable for use WiH'lPYl'l ii isdcsircd to mount a large number of r singli-so kois upon su h a support, nnd whilc I have 4 5 des ribed 1hrconstruction of said sockets with particuiar ri-l'orom-o in tho iii-mils oi their construction, l am IlWzll'" that many r-huugos may he made therein. and i.

d uni wish iolimfi mysoll'iosaid dvluiisiurther than is ilil!I( i in tho nppondi-d claims.
